Polymer electrolyte membranes

Patent Granted Polymer electrolyte membrane (PEM) electrolysis is the electrolysis of water in a cell equipped with a solid polymer electrolyte (SPE)[1] that is responsible for the conduction of protons, separation of product gases, and electrical insulation of the electrodes. The PEM electroyzer was introduced to overcome the issues of partial load, low current density, and low pressure operation currently plaguing the alkaline electrolyzer.
